Thoroughly wash feeding container and all utensils, then boil for 5 minutes. Set aside on a clean surface. In a separate pan, heat water to a rolling boil for 5 minutes and allow it to cool. Pour the correct amount of warm (previously boiled) water into the sterilized feeding container. Fill enclosed scoop by pressing against the tin, then scrape level with the straight edge of a knife. Add one level scoop of powder to each 60 mL of water. Mix until completely dissolved. Test temperature and feed. Once the feeding begins, discard unused formula within 1 hour. Additional feedings may be stored in refrigerator (2-4 ° C) for 24 hours.
